be at least the lease duration, which is typically 1-2 minutes.
It seems prudent for the experimental NFS client to wait a few
seconds before retrying such an RPC, so that the server isn't
flooded with non-recovery RPCs during recovery. This patch adds
an argument to nfs_catnap() to implement a 5 second delay
for this case.

pmap_ts_referenced() is not always appropriate for checking whether or
not pages have been referenced because it clears any reference bits
that it encounters. For example, in mincore(), clearing the reference
bits has two negative consequences. First, it throws off the activity
count calculations performed by the page daemon. Specifically, a page
on which mincore() has called pmap_ts_referenced() looks less active
to the page daemon than it should. Consequently, the page could be
deactivated prematurely by the page daemon. Arguably, this problem
could be fixed by having mincore() duplicate the activity count
calculation on the page. However, there is a second problem for which
that is not a solution. In order to clear a reference on a 4KB page,
it may be necessary to demote a 2/4MB page mapping. Thus, a mincore()
by one process can have the side effect of demoting a superpage
mapping within another process!
currently supporting sparc64. After a `make depend all` there are
three programs; testsoftfloat for testing against the SoftFloat in
src/lib/libc/softfloat for reference purposes, testemufloat for
testing the emulator source in src/lib/libc/sparc64/fpu and testfloat
for testing with the installed libc. Support for other architectures
can be added as needed.

o) Set a local maxmem in sb_machdep.c to avoid trying to use pages over 2^64
under 32-bit ABIs. Our pmap needs corrected to use vm_paddr_t consistently,
then we can make vm_paddr_t 64-bit under 32-bit ABIs and add code in pmap
to limit phys_avail by the maximum PFN that a 32-bit PTE can hold.
Some of these cases should be safe in a non-atomic fashion, however
since all of the driver ioctls are locked, a lot of work is required to
fix it correctly. Just don't sleep now.

- Rework the wrapper support to check libpkg version as well as pkg_install
version.
- Add libfetch to _prebuild_libs.
- There are no new features introduced.
Notes: the API is not stable, so basically, do not use libpkg in your
projects for now. Also there's no manpage for libpkg yet, because the API
will change drastically. I repeat, do not use libpkg for now.

with delegations enabled, the recovery could fail if the renew
thread is trying to return a delegation, since it will not do the
recovery. This patch fixes the above by having nfscl_recalldeleg()
fail with the I/O operations returning EIO, so that they will be
attempted later. Most of the patch consists of adding an argument
to various functions to indicate the delegation recall case where
this needs to be done.

This time, abandon the use of busdma and start interacting with the VM
system directly. Make use of the new kmem_alloc_attr() which allows us
to easily allocate non-contiguous pages to back the GART table. This
should help a lot when starting or restarting X after the system has
been running for a while and memory has become fragmented.

In the 'ln source... directory' synopsis, the basename of each source
determines the name of the created link. Determine this using basename(3)
instead of strrchr(..., '/') which is incorrect if the pathname ends in a
slash.
The patch is somewhat changed to allow for basename(3) implementations that
change the passed pathname, and to fix the -w option's checking also.
The code to compare directory entries only applies to hard links, which
cannot be created to directories using ln.
Example:
ln -s /etc/defaults/ /tmp
This should create a symlink named defaults.

proper device_t so it faked the devctl event to appear like one, this is now a
notify which allows more information to be passed.
We notify for both the device attach/detach and for each usb interface. A devd
rule can now match on the interface properties, including composite devices
which may have a uvideo interface and also usound and possibly uhid too.
An example to match a umass device with a scsi subclass and BBB protocol would be
notify 100 {
match "system" "USB";
match "subsystem" "INTERFACE";
match "type" "ATTACH";
match "intclass" "0x08";
match "intsubclass" "0x06";
match "intprotocol" "0x50";
action ...
};
The old attach devctl event has been retained for the moment to make merging to
8.1 easier. This was never compatible with 7.x or earlier due to the ugen regex
change needed.
